Well you could just build your SQL Query Dynamically...

<pre><code>string [] searchWords = searchTerm.Split(",");

string SQL = "SELECT col1 FROM myTable WHERE 1=2";

foreach (string word in searchWords)
{
 SQL = string.Format("{0} OR contains(fts_column, '{1}')", SQL, word);
}

//EXEC SQL...
</code></pre>

Obviously this comes with the usual warnings/disclaimers about SQL Injection etc... but the principal is that you would dynamically build up all your clauses and apply them in one query.

Depending on how your interacting with your DB, it might be feasible for you to pass the entire un-split search term into a SPROC and then split &amp; build dynamic SQL inside the stored procedure.

blocks|key|672522|text|FREETEXT可能对您有效。它会根据单词边界将字符串分成单独的单词(断字)。那么您将只有一个SQL调用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|672523|MSDN+--+FREETEXT|offset|length|672524|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/en-us/library/ms176078.aspx^0|0|0|G|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

FREETEXT might work for you. It will separate the string into individual words based on word boundaries (word-breaking). Then you'd only have a single SQL call.

blocks|key|4735478|text|您可以执行类似的操作:只需根据分隔符解析搜索词，然后对每个分隔符进行调用，将结果连接在一起。或者，可以执行多个CONTAINS：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4735479|SELECT+Name+FROM+Products+WHERE+CONTAINS(Name,+@Param1)+OR+CONTAINS(Name,+@Param2)+etc.|code-block|syntax|javascript|4735480|也许两个都试一下，看看在你的环境中哪一个更快。|4735481|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

You could do it similar to what you have there: just parse the search terms based on delimiter, and then make a call on each, joining the results together. Alternatively, you can do multiple CONTAINS:

<pre><code>SELECT Name FROM Products WHERE CONTAINS(Name, @Param1) OR CONTAINS(Name, @Param2) etc.
</code></pre>

Maybe try both and see which is faster in your environment.

I've got a search box that users can type terms into. I have a table setup with fulltext searching on a string column. Lets say a user types this: "word, office, microsoft" and clicks "search".

Is this the best way to deal with multiple search terms?

<pre><code>(pseudocode)
foreach (string searchWord in searchTerms){ 
 select col1 from myTable where contains(fts_column, ‘searchWord’)
}
</code></pre>

Is there a way of including the search terms in the sql and not iterating? I'm trying to reduce the amount of calls to the sql server.
